The Trade Me Property Price Index measures trends in the expectations of selling prices for residential property listings added to Trade Me Property by real estate agents and private sellers over the past three months.
It provides buyers, sellers and realtors with insights into ‘for sale’ price trends by property type and property size.
The Index is produced from data on properties listed on Trade Me Property in the three months leading up to the last day of each period. Each period’s value is a truncated mean of the complete three months’ worth of listings. This is to better reflect trends in property prices rather than month-to-month fluctuations in housing stock.
The Index uses an “80% truncated mean” of the expected sale price to calculate the average asking price. This excludes the upper and lower 10% of listings by price, and averages the expected sale prices of the remaining properties.
It provides an insight into ‘for sale’ price trends by type and size of property. Other reports aggregate property price data across these various properties.
